Control Software Program
The control software program, written for DOS based PC’s, is
included in the evaluation kit. This software supports operation
of the evaluation circuit board in basic quadrature ASK and FM
modulation configurations
The control software MAIN MENU offers six submenus for
various configuration selections and three command actions.
The menu tree is illustrated in Figure 1.
The 7 configuration submenus are:
• Board Configuration Menu
• Modulator Channel 1 Configuration Menu
• Modulator Channel 2 Configuration Menu
• Modulator Channel 3 Configuration Menu
• Modulator Channel 4 Configuration Menu
• Configure Board Menu
• Test Menu
The four command actions are:
• Load Configuration File
• Save Configuration File
• Compute Registers
• Exit
A typical operational sequence is:
A. Load Configuration File
Executing MAIN MENU item (5) brings up a screen with the
current file name and requests the name of the file to be
loaded. Once the new file name is entered, this command
loads the configuration setup and returns to the MAIN MENU
screen. This command allows the user to select a previously
saved configuration file for display, review and editing.
B. Edit Configuration File
This is done by sequencing through each of the configuration
submenus and adjusting the parameters for the desired
hardware configuration.
- The BOARD CONFIGURATION MENU is used to select
control interface type, printer port (PRN) number, FPGA
addressing, and oscillator frequency.
- The MODULATOR CHANNEL CONFIGURATION
MENUS are used to select carrier center frequency, input
sample rate, modulation type, coefficient file name,
interpolation factor, impulse response length, Stimulus file
name, number of data samples, output attenuation, output
enabling, cascade input control, synchronization,
synchronization polarity, FIFO depth, Output Format, and
test register settings. There is a menu for each of the four
modulator channels on the evaluation board.
C. Save Configuration File
Executing MAIN MENU item (6) brings up a screen with the
current file name and a request for a file name to be saved.
Once the new file name is entered, this command stores the
configuration setup to the new file.
WARNING: Failure to change the .cfg file name may result in overwriting of
an example file with an edited version of that file.
D. Compute Registers
This command will use the configuration data entered in MAIN
menu items 0-4, and generate a number of files which contain
the register values for the IC’s on the evaluation circuit board.
The computation is based on a .cfg file, which contains filter
(.imp) and stimulus (.imp) files for each of the 4 channels. The
computed register values are stored in a set of files identified by
the suffix of .1, .2, .3 and .4, indicating the channel to which the
parameters apply. The actual filename preceding the .1, .2, .3
or .4 suffix is automatically assigned to be the Configuration file
filename.
